Spatial distribution of epicenters (circles) and stations (blue squares) used in this study [left panel Period I, middle panel Period II, and right panel Period III (Dojo and Hiramatsu 2017)]. Stars in the middle panel are the epicenters of the 2004 Chuetsu earthquake and the 2007 Chuetsu-oki earthquake. Red lines and triangles, respectively, show Quaternary active faults and volcanoes. In the lower-left panel, the analyzed area is shown by a square, the Itoigawa–Shizuoka Tectonic Line (ISTL) by red lines, and the Niigata–Kobe Tectonic Zone (NKTZ) by a gray zone
